Description
One, technical field
The present invention relates to a kind of flexible pavement be carried out the equipment of repairing the roads of regeneration repairing, particularly relate to a kind of microwave heating device for asphalt pavement and reparation machine thereof.
Two, background technology
Tarmac road (being flexible pavement) almost spreads all over the various places, town and country.But asphalt surface is because of the influence of its main material (pitch) character (heat soft, cold short): just can occur damage in various degree after using two, three years.Its main cause has two aspects: the one, summer the temperature height, the road surface deliquescing is easily rolled modification by heavy-duty vehicle, change uneven: the 2nd, when winter, temperature was low, supercrust became fragile, and was easily pressed crisply again, various cracks occurred.Along with the appearance of various oversize vehicles and the situation of the serious overload of transport vehicle remain incessant after repeated prohibition again.The impaired speed in road surface can be more and more faster, especially in two seasons of winter in summer.
At present the method that solves is nothing but sectional repair or removes heavily shop, but the cost height, and time-consuming, effort had not only been wasted resource but also contaminated environment.
China's speedway medium pitch road surface accounts for the overwhelming majority in addition, and these road surfaces various forms of infringements can occur inevitably under the influence of long-term natural environment and driving use.Thereby press for the small-sized flexibly pavement patching machinery of advanced person, dependable performance, construction, and utilize on-the-spot heat utilization of bituminous mixture and regeneration techniques, can solve asphalt pavement pit with having with the problem of mending.Heating technique commonly used at present has visible light, infrared rays etc.First kind of visible light heating though realize that easily heat penetration is little, is difficult for being absorbed by flexible pavement, so heat time heating time is long.Second kind of infrared radiation heating, existing practical application, but that this technology still can not solve heating is inhomogeneous, easily make ageing of asphalt, and still fail develop the selective coating material that with flexible pavement be complementary at present, thereby the efficiency of heating surface is not high, and problem such as vehicle-mounted poor-performing.
Microwave energy has obtained ripe relatively application industrial, all achieve notable results in industries such as food, grain, tobacco, medicine, but also belonging to new trial aspect the flexible pavement heating, though have some enterprises, company to develop the microwave heating plate of flexible pavement, but the efficiency of heating surface is low, prevent microwave leakage, and perfect inadequately to constructor's protection aspect; And after heating, can not stir timely and shakeout; Construction effect is not very desirable.
